Abstract

Concrete is a construction material that is often used in building construction. Concrete is a mixture consisting of coarse aggregate and fine aggregate mixed with water and cement as a binder and filler, and additives are often added. Bagasse fiber has the criteria needed to be used as an added material for strengthening concrete. The variations of bagasse fiber used were 0%, 2.5%, 5%, 7.5% and 10%. The results showed a decrease in the slump value, this was due to the higher variation of bagasse substituted for the weight of cement with the same FAS value, which would reduce the workability of the concrete. The compressive strength of concrete with variations of sugarcane fiber decreased. The highest compressive strength value is found at 0% variation, namely 20.93 MPa, this is due to the greater percentage of bagasse fiber mixture, the concrete that should be filled with aggregate is filled with sugarcane fiber, causing the compressive strength of the concrete to decrease.

Abstract

PT. XYZ is a company engaged in the manufacturing sector (manufacturing automotive spare parts) with a production process using fine blanking machines and international standard press machines. Based on the data obtained, related to product quality, there are problems that occur during the production process and product results. These problems are related to the level of defects in the production process. From historical production data from July to November 2022, sprocket products contribute the most defective products, both congenital physical defects of the material itself and during the production process such as dakon, scratch, crack/hadan, and burry, which can affect the quality specifications that have been set with a tolerance limit of 0.4%. In general, defective sprocket products can still be reworked, but it takes a long time, so the company will be greatly disadvantaged because production costs will soar. Therefore, based on these problems, the researcher uses the American Military Standard (Mill STD 105D) and American Military Standard (Mill STD 414) methods, which aim to look at aspects of the causes of defects, the level of defects on sprockets, and provide advice to companies on how to minimize sprocket product failure. Based on the results of research conducted on quality control planning using this method, it is known that the results of inspection can be accepted as passing when the number of variable defects is less than 6 pcs in 13 pcs for major defects, while minor defects can be accepted as passing when the number of attribute defects is less than 15 pcs in 200 pcs.

Abstract

In pace with the rising output of electric vehicles, the nickel sector is still developing quickly. In 2022, Indonesia will manufacture 500,882.27 tons of ferro nickel, of which 197,758 tons, or 30.01%, will be able to be sold. Along with the growth of nickel mines comes technological advancements, one of which is the ability to manage wasted ore, a waste product of the nickel refining process. With the help of this study, used ore will be transformed into a useful product that can be used to control the environment. Laboratory scale testing, field scale tests, and toxicity tests (TCLP and LD50) are the techniques used. Testing for toxicity and planting on 14 tonnes of wasted ore, a byproduct of hydrometallurgical heap leaching. Limestone or a combination of biolite, agromax, and ND-201® were used to neutralize the spent ore and Fe residue composites during the process. This seeks to make the leftovers from the leaching process, the resulting runoff water, and the plants that can come from it edible. According to the test results, processed spent ore is a harmless substance that does not fall under the B3 waste category and may be utilized as an excellent planting medium for perennials and food plants. Based on BPOM quality criteria in Law No. 23 of 2017, the results of food laboratory testing revealed that food crops grown through the planting procedure utilizing discarded ore media were suitable for eating.
